If running EASE always causes Autodesk AutoCAD (or a related product) to run its installation routine, this is most likely an indication that the installation of AutoCAD was somehow corrupted and needs to be repaired. To correct this problem please go to the Windows Control Panel, choose Programs and Features, then click on Autodesk AutoCAD (or the related product) to perform a repair or reinstall.
AURA is a highly sophisticated room-acoustic module. It has been integrated into EASE, based on the CAESAR software from Aachen University. It can be considered as consisting of two different engines. One method is utilized for highly accurate auralisations at selected receiver positions, it is called AURA Response. The other one is less precise but much faster and therefore allows for the calculation at many points, that means AURA Mapping.
EASE is a software that allows the creation of a 3D acoustic model of a room and a sound system within a room.
First the geometric data for the room is entered, then data for the acoustic absorption of the materials that are on the walls and other surfaces. From this, reverberation times and other acoustic parameters can be computed, and the model can be used to test various modifications that might be made to the acoustics.
AFMG develops software on the current state-of-the-art level.
EASE’s algorithms have repeatedly been tested to perform as intended. Sufficient proof has been published in renowned magazines and textbooks. For example, the latest paper addressing speech intelligibility can be found here: http://www.aes.org/e-lib/browse.cfm?elib=16985
In order to assess if a project can be simulated adequately based on the room´s characteristics it is important to know about the different calculation methods used within the different versions of EASE.
AFMG offers three calculation levels within the product family of EASE – the industry standard electro-acoustical simulation software:
Not all GLL files are the same. Some AFMG® programs have specific requirements for a GLL in order that the program is permitted to use the GLL. EASE® as well as the EASE GLL Viewer can use all GLL types without restriction.
1 GLL Types
The chart below summarizes what types of GLLs can be used in each AFMG program.
Accurate loudspeaker data is necessary for reliable simulation results.
As a manufacturer you can measure and create loudspeaker data yourself. In addition to the proper equipment, you would need in-depth knowledge about the measurement techniques to adequately model the loudspeaker behavior. For this please refer to SpeakerLab’s comprehensive User´s Guide which can be found under the link below.
In this manual you will find step-by-step instructions for the most common cases along with related references:
Adding your data to the EASE® loudspeaker database is free of charge. It requires collecting selected loudspeaker performance data and converting it in a binary format.
Acoustic, electronic and mechanical data of the sound source must be assembled in a single data file, the so-called GLL. This GLL file can also include your logo and company information.
